legs, but apparently no actual isolated elongate scales as in 

 P. alhonirjra. Wings with hairs situated on the veins only, rich 

 brown in colour, showing golden brown with violet iridescence in 

 certain lights. No surface-scales on the wings, the only ones- 

 present being the small ones forming the spots at the tips of the 

 A^eins ; black bristly hair-spots at tips of practically all the veins ; 

 some white scaly hair-spots near tips of some of the veins, and a. 

 few on each of the two lower branches of the 2nd longitudinal 

 vein and both branches of the 4t!i vein, all placed at a little before 

 their tips ; a larger white scaly hair-spot near the base of the 

 costa, and some isolated erect white hairs ])laced irregularly here 

 and there on the veins. The 2nd longitudinal vein forks imme- 

 diately beyond the base of the 3rd vein, the upper branch of the 

 former forking barely beyond the middle of the wing, and very 

 little beyond the fork of the 4th vein. 



Length about 1| millim.
